I have no doubt at all that most of the losses on this service are the result of phishing, but also that there have been some hard-to-explain cases over the years that have indicated that from time to time someone apparently finds some security holes he uses to hack. There is no great wisdom here, you just need to change the way you think - everything that is entrusted to another to keep is not really yours. You log in to your account, you see that balance is 0 and that's where the whole story ends - support has never been and will never be of much help.
